Application filed March 17,

To all whom it me?! foneern Be it known that I, 'Pnoxor J. liioKoP, a subject-of the Emperor of Bohemia, and a .resident of New York, in the county of New York and State of New York, have invented certain new and useful AImprovements in Kinetoscope-Film Magazines, of- Which the following is a'specification. My invention relates to the re-wind magazines of motion picture projectors, and the main -object thereof is to provide such a magazine from which vthe filmmay be fed into the projector for another projection without the necessity forthe. intermediate reversewinding now common, thereby saving much time and greatly reducing the wear on My invention is fully described in the following specification, of'xvhich the acco m 2o panyingdrawings form a part, in which like characters refer to like parts in each of the' ',views, and inwliichz- Figure v1 isV a.' front; View, partly 'broken away, of a'magazine constructed in accordance'with my invention; Fig. 2 is asection taken on thelineA 2 2 of Fig. 1; Fig. 3 is an enlargedfragmentary lView of-a detail; and Fig. 4 is an enlarged fragmentary sec' 'tion taken on the line 4--4 of Fig. 1.

3Q 'Referringto the drawings, 5 represents a circular casing having a raised portion 6, in the form of a sector of a circle, upon one face thereof, this portionA 6 being slotted at' 7 and being of .a slightly greater depth than 35 the width of a motion picture film, and the l casing 5 is likewise of 'a depth slightly exceeding the width of the film, thereby making the casing 5 and raised portion 6 jointly of more than double the width of the film.

- Carried in a small casing 8 at the, opposite Afaceof'the casing 5 is a shaft 9 having a v'pulley 10 thereon and connected with a film I carrier drum 11 within the casing 5 and of only slightly less diameter,`the connection l between pulley 10. and shaft 9 being by means of a friction clutch 12, the said pulley being-driven by a belt 13 connected with the re-wind .pulley of a projector upon which my magazine'is adaptedto 'be removably mounted in 'any desired manner, this not being illustrated as it forms no` part of the! invention.

Within the casing 5 is an immovable central support 14 for a plurality of radially' arranged telescopic arms 15,:shown as 5 in number but a greateinumber of which will Specication ot Letters Patent. i

preferably be used, each of said arms being maintained in extended condition by means of a contained spiral 'spring 16, and I provide a yroller 1T atthe end of each arm. Two 50 of these arms 15, at the Sides of the raised portion 6 of the casing, are joined by means of toggles 18 desired ones of which fare guided on radial rods 19 to maintain the same in operative relationship, as well as 'fabric strip 24 and the inner b v a-fabric strip 25, these strips jointly forming a chaunel open at its inner edge for the reception 7 5 and guidance of the film', as will be later ex plaiiied.

21,`24, a1id'25,1the toggles 1S, the fingers 2( and the bars 22 and 23 may more toward the-f8() center of the casing alongr radial lilies in the collapsing of the telescopic arms 15 into the positions indicated by dotted lines in Fig. 1,

approximately, the flexible strips 2l and 25 becoming looped between the adjoining silpporting bars as indicated at 26 and which loops n iay fold down o ne over the other by the pressureV of the film thereon.

The outer sections of the telescopic arms 15 may .carry perforated ears 2T adapted to 90 be engaged by hooks 2S on a button .29 normally held toward the frontof' the casing by means of a spring 30, this engagement of tlie said ears being automatic when the arms 15 are entirely collapsed with the film 95 wound thereon, but depi'ession of the button 29 will releasethe arms 15 and permit the springs 16 therein .to again extend the saine. By reference to Fig.- 2 it will be noted that the channel 31 formed by the fabric 100 strips 21, 24 and 25 is at an incline to the plane of the front and rear faces of the casing 5 and `the forward end vthereof is the casing 5, thereby permitting the film at the forward end of said channel to clear the film already wound upon the telescopic arms 15.

In practice, the starting end of a film 11o after 'having been passed through a projector is threaded into the' channel 31, noir in itsoiiterinostposition, and the. end of' the iilin is then doubled around a rolleil 32 on carrier drum 11, Fig. 3, and. locked in place by a slide 33, the tilin being` Upon the inner side of said carrier drinn` As 'the' drinn 1l is revolved the ilin end engaged thereby is carried around the rollers 1T on the successive telescopio zii-ins l5 and is con* tiniioiisl'if' drawn Vthrough the Channel 3l as it emerges from. the projector and :torined linto successive layers, one ivitliin another,

spondingly until the entire ilin is .Wound tliereon but it lwill be noted that the. starting end ofthe filin at the outer surface of the reeled ilin readgiT Afor entrance linto a projector Without the iieeesityv :for re,-K versely winding the saineas is at present necessary.y
